22. VARIOUS PROTECTIONS
1. DISCHARGE GAS TEMPERATURE OVERRISE PREVENSION CONTROL
The discharge gas thermosensor (discharge thermistor : Outdoor side) will detect discharge gas
temperature.

104°C 101°C 110°C
When the discharge temperature becomes higher than Temperature ,the compressor frequency
is decreased 20 Hz, and it continues to decrease the frequency for 20 Hz every 120 seconds until
the temperature becomes lower than Temperature .
When the discharge temperature becomes lower than Temperature ,the control of the control of the
compressor frequency is released.
When the discharge temperature becomes higher than Temperature ,the compressor is stopped
and the indoor unit LED starts blinking.

2. CURRENT RELEASE CONTROL
The compressor frequency is controlled so that the outdoor unit input current does not exceeds
the current limit velue that was set up with the outdoor temperature.
The compressor frequency returns to the designated frequency of the indoor unit at the time
when the frequency becomes lower than the release value.
